“God said to Moses, ‘I AM WHO I AM. This is what you are to say to the Israelites: ‘I AM has sent me to you.’” ~ Exodus 3:14 NIV
For God to introduce Himself in that way… Out of all the names He has, He used “I Am.” If someone were to ask me who is the deity I worship, well I’d obviously respond with “God.” Jesus, Lord, Father, Yahweh. I mean there’s a whole list of names that we can choose from. But “I Am” encompasses much more because God is so much more.
I majored in English so my English grammar nerdiness came out during a life group study on the book of John. John came before Jesus to make way for His coming, and the way Jesus would be revealed was that the Holy Spirit would reveal the Son of God. John the Baptist says in John 1:31, ”’I myself did not know him, but for this purpose I cam baptizing with water, that he might be revealed to Israel”’ (ESV). Later he says in John 1:33, ”I did not know [Jesus], but [God] who sent me to baptize with water said to me, ‘He on whom you see the Spirit descend and remain, this is he who baptizes with the Holy Spirit”’ (ESV). In order words, we see here that God sent the Holy Spirit, and that the Holy Spirit revealed who Jesus was and if Jesus is God based on the trinity, then the Holy Spirit reveals who God is.
(Trust me, I didn’t come up with this all by myself. This is something that my life group thoroughly studied and most of them are either theology majors or studying theology.)
So, if God calls Himself “I Am”, we can change the pronoun and verb but not change the meaning of the phrase “I Am.” I would then become God—a proper noun—and am would then be is—another form of the being verb. Now we have “God is.” And what does the Holy Spirit reveal who God is?
”God is love.” ~ 1 John 4:8
”May the God of hope fill you with all joy and peace as you trust in him, so that you may overflow with the hope by the power of Holy Spirit.” ~ Romans 15:13
”The Spirit of the Lord will rest on [Jesus]—the Spirit of wisdom and of understanding, the Spirit of counsel and of power, the Spirit of knowledge and of the fear of the Lord—.” ~ Isaiah 11:2
”Then [God] said, ‘I am the God of your father, the God of Abraham, the God of Isaac and the God of Jacob.”’ ~ Exodus 3:6
”Jesus answered, ‘I am the way and the truth and the life. No one comes to the Father except through me.”’ ~ John 14:6
”’I tell you the truth,’ Jesus answered, ‘before Abraham was born, I am!”’ ~ John 8:58
(There are so many more verses that share who God is but this is just a small glimpse.)
So who is God? God is I Am. Therefore, God is God.
